Product details
Overview
PZU13B3A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 13 V nominal working voltage, 320 mW total power dissipation at 25 °C ambient, and 10 A non-repetitive peak reverse current. It delivers hard breakdown knee, low dynamic impedance at 5 mA, and intentional minor leakage optimization for fast switching and noise reduction in precision reference and overvoltage clamp circuits.
For engineers reviewing the PZU13B3A,115 datasheet, PZU13B3A,115 pinout, PZU13B3A,115 application, or PZU13B3A,115 equivalent, this device serves as a compact, surface-mount voltage reference with verified thermal resistance of 255 K/W (junction-to-solder point), stable temperature coefficient of +2.5 mV/K at 5 mA, and differential resistance ≤80 Ω - critical for low-drift biasing and transient suppression in space-constrained DC-DC feedback paths.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable 13 V reference across load variations and input fluctuations. Its design incorporates optimized doping and junction geometry to achieve tight ±2 % tolerance (B3 series), low leakage at 0.5 mA (≤10 nA), and controlled temperature coefficient (+2.5 mV/K) for predictable drift behavior from 25 °C to 150 °C.
The SOD323 package enables high-density PCB layouts while supporting both reflow and wave soldering per IPC-7095 guidelines. Thermal performance is characterized with Rth(j-sp) = 255 K/W on FR4 with 1 cm² cathode pad, enabling reliable operation up to 150 °C junction temperature under pulsed surge conditions (tp = 100 µs, square wave).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 13 V at IZ = 5 mA - defines precise regulation point for feedback networks and voltage clamping |
| Tolerance | ±2 % (B3 series) - ensures consistent reference accuracy without post-production trimming |
| Differential Resistance | ≤80 Ω at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Reverse Current | ≤10 nA at IZ = 0.5 mA - reduces standby power loss in battery-backed circuits |

|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck-boost converters using optocoupler-coupled feedback loops. IC Role / Device Role / Timing Role: Provides stable 13 V reference to TL431 or similar shunt regulator IC, defining primary-side voltage setpoint. Use Value: ±2 % tolerance and +2.5 mV/K TC ensure <±1.5 % total output error across –40 °C to +125 °C operating range. |
Use Scenario: Protecting microcontroller I/O pins from ESD or inductive kickback in industrial sensor interfaces. IC Role / Device Role / Timing Role: Acts as bidirectional transient suppressor between signal line and ground, clamping spikes above 13 V. Use Value: 10 A surge rating (100 µs) and ≤80 Ω impedance limit clamping voltage to <14.5 V during 1 kV EFT events. |
| Low-Power Sensor Biasing | ADC Reference Stabilization |
Use Scenario: Supplying excitation voltage to resistive temperature detectors (RTDs) or bridge sensors in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Delivers low-noise, temperature-stable 13 V bias to sensor elements with minimal quiescent current draw. Use Value: ≤10 nA reverse leakage at 0.5 mA preserves multi-year battery life; hard knee prevents bias droop during sensor self-test pulses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B13,115 | Same 13 V, ±2 %, SOD323, but higher typical differential resistance (120 Ω vs. 80 Ω) and no intentional leakage optimization | Lacks AN90031 noise-reduction tuning; less suitable for high-speed switching nodes | Prefer when lowest cost is prioritized and noise sensitivity is low |
| MMSZ4688T1G | 13 V, ±5 % (B series), SOD123 package (larger footprint), 500 mW Ptot, Rth(j-a) = 390 K/W | Higher power handling but poorer thermal performance and looser tolerance | Choose only if board layout permits larger package and ±5 % accuracy is acceptable |
Compared with BZX384-B13,115 and MMSZ4688T1G, PZU13B3A,115 offers superior regulation precision (±2 %), lower dynamic impedance (80 Ω), and purpose-built leakage characteristics for noise-sensitive applications - making it optimal for compact, high-fidelity voltage references where thermal and electrical stability are critical.

FAQ
What is the maximum continuous reverse current for PZU13B3A,115 at 25 °C ambient?
The device is rated for 200 mA maximum forward current, but as a Zener diode, its continuous reverse current is limited by power dissipation. At 25 °C ambient on standard FR4, Ptot = 320 mW implies IZ ≤ 24.6 mA (320 mW ÷ 13 V) for steady-state operation without exceeding thermal limits.
Does PZU13B3A,115 meet JEDEC moisture sensitivity level (MSL) requirements for reflow?
Yes - the SOD323 package is rated MSL 1 (unlimited floor life) per J-STD-020, with peak reflow temperature support up to 260 °C, confirmed by Nexperia's qualification testing and documented in the product's reliability report.
How does the +2.5 mV/K temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
With a nominal 13 V Zener voltage and +2.5 mV/K TC, the total drift is approximately +438 mV (165 K × 2.5 mV/K), resulting in a worst-case regulation range of 13.0 V to 13.44 V across the full temperature span - within specification for most non-precision analog systems.
Can PZU13B3A,115 be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, slight VZ mismatches cause current hogging. Parallel operation is not recommended; use a single higher-rated device or active regulation instead.
